Outfitting gives a reason for not being able to sell a module

[CMDR Charybdis]

This one is a usability improvement to the outfitting screen. When selling modules that can carry content (cargo racks or passenger berths), and are in use, then grey out the sell button and give a reason why it can't be sold.

I almost raised a bug about this for the Chieftan in Beta 3.0 before I realized I'd fallen into an old trap (in this case transferring cargo after buying the ship for the first time).

Yes have to agree on this one. I used to do a lot of user interface stuff at my old job, and errors that don't explain themselves are something that we always fixed (any good interface designer would). We called errors like this "silently failing". Ideally it would give you the option then and there to correct the problem (in this case, sell the cargo), so you don't have to waste time going back and forth in menus.
